Studies on Hybrid Sorghum Seed Production Application, of NPK at Different Levels and Combination on the Yield and Quality of CSH-5 Hybrid Seed

Abstract

A field experiment conducted to find out the effects of application of N at 0.100 and 200 kg/ha and P and K each at 72.5 and 145 kg/ha in different combinations on the growth of ms 2077-A (female parent of CSH-5) and yield and quality of CSH-5 hybrid seeds revealed. (1) hybrid seed yield varied from 1079 to 2292 kg/ha ameing the treatments; (i) the bulk seeds could be separated into three size grades, of which 49.5 per cent was retained in 7x7 sieve; (iii) germination and seed vigour were asso- ciated with seed size and (iv) the thousand seed weight was influenced by the dos of P.
